This invention is in the nature of an improvement on the machine disclosed in my pending application. Serial No. 658.153, filed Nov. 2nd,

omitted from the drawings hereof to simchines 'inl ltheother respects hereinafter de- Y scribed va'nd claimed. i

Q Figurellis a longitudinal sectional eleva- ""tioli".o'^f"a `typewriting machine embodyingthe invention. `parts of the ina'chine being omittedfto simplifv the drawing. I.. i Qand are' ti-agmentaniv longitudiAA tsnal sectional elevationsy on line 2 2. lfig. l. respectively. sho'wlng the space bar 1n the plifythe same can be the same as the corresponding parts shown in said application.

The main frame of the machine. as in said other machine. is composed of a stationary base frame or part A adapted to rest on a supporting surface, and a movable frame or part B, which is pivoted at its front portion to the front portlon of the stationary frame so that the rear portion of the movable frame. which supports the platen carriage can swingr to lower the carriage from an elevated operative position to an inoperative position in rear of the type-bars, which are mounted in the stationary frame. but the `pivotal connection of the frames is located view, partl` i the key actions and other parts.

1911, and most of the parts.

The frames are pivotally connected prefera-bly by screws C which are screwed tightly into threaded holes in the sides of the stationary frame and have large heads tting in circular holes in the sides of the movable frame, which are located outside of the sides of the stationary frame. The movable frame can be stationarily secured in its raised and lowered positions to the station- Iary frame by any suitable means, such as thumb screws c carried by the sides of the movable frame and adapted to be screwed into upper or lower holes c c2 in the sides of the stationary frame, as in said other machine.

D represents the platen which is journaled in a carriage which can be constructed and ar anged to travel crosswise of the machine on a guide track Il on the rear end of the movable frame B, as disclosed in said application or in any other suitable manner.

E represents one of the type-bars which are pivotally mounted in any suitable way on a supporting segment e so as to swing upwardly and rearwardly to print at the front side of the platen. Each typebar has a plurality of type, preferably three, and the segment is secured on a shift frame F which is pivoted in the stationary frame A to swing up' and down for printing ditferent case characters. The shift frame is pivoted to swing about an axis coincident or substantially coincident with the pivoted axis of the movable main frame B. the shift frame preferably having forwardly diverging' arms pivoted on the reduced inner endsofV the pivot screws C for the niain frame. The shift-frame and the movable main frame B can. however. be pivoted in any other suitable way enabling them to swing about a common or substantially coniinoncenter.

f represent shift keys such as shown in said application provided with cani portions engaging a roller f2 on the shift faine for shifting the shift frame up and down, `f" represents a cross rod which rigidly connects the sides of the shift frame and serves to support the type basket or back stop f* for the type-bars.

(.ir represents the finger keys for actuating the type-bars. Tlicf are provided with key stems g g g2 of as many different t'orins as there are banks of keys, there being iii the construction shown. three banks of keys and three different forms of stems. Each key stein is pivoted to a pair of parallel supporting links h which are pivoted to and extend rearwardly, one above the other from the front cross-bar?) of the movable frame B. The lower portions of all of the key stems. which are p'ii'fited to the linksare arranged side by side ina single transverse row or plane. and the upper portions of the key stems y extend substantially directly upwardly from their connections with the links li while the upper `portions of the stems g" extend forwardly and upwardly and the u'pper poi-tions of the remaining stems g2 extend rearwardl and upwardly from their Connectionswit ythe links h, thus locating the finger :keys in three transverse banks or rows, one infront and one in the rear of the middle bank or row of keys on the straight key stems y. Preferably the upper links enter vertical slots h2 in a rearwardly projecting upper edge of the cross-bar and are pivoted on a single pivot wire ha while the lower link. .are similarly pivoted in slots in the lower edge4 of the bar on a second pivot wire h4. Each slotted edge of the bar b is cut lengthwise at h" intersecting theslots, see Fig. 6 and the bottom of this out is planed out to form a seat for the pivot wire and prevent its lateral displacement. The pivot wires h3 fr extend from end to end of the cross-bar and are held from longitudinal movement by the sides of the frame B'. In this way the links for the w'holeseries of keys are pivoted on two pivot wires. which greatly simplifies the manufacture, while. nevcrtheless. providing strong stable pivotal connections affording ample lateral support for the links.

I represents connecting links pivoted at their front ends to depending legs 'L' on the upper key supporting links k and pivoted at their rear ends to the type-bars. All of the pivot joints between the connecting links I and the key supporting links l` are located on a single line z" coincident or substantially coincident with the pivotal axis of the frame B and the shift frame F. This arrangement insures the saine action of the keys and typebars in all positions ofthe shift frame. and when the machine is collapsed the finger keys and theirl supporting stems and links can swing with the frame B about the line z" from their operative position to the collapsed position shown in Fig. T. from which it will be seen that the high rear portion of keyboaid moves downwardly and rearwardly toward the type-bars while the front portion thereof and the front end of the movable frame B move upwardly and rearwardly thereby decreasing `both the height and length of the machine from front to rear.

K re )resents the universal bar, which is prefera lv suspended by upri ht end legs k and a middle leg k entering s ots in the upper edge of the cross-bar 7i and pivoted ou the pivot wire h3 in the same manner as the upper key supporting links h. The universal bar is located in front of. and is adapted to be struck and moved forwardly by the legs z' of the upper key supporting links li when the keys are depressed, as shown in Fig, L The middle leg ofk the universal bar is pivoted to the front end lo1 a rod or link L which passes rearwardly and upwardly between the two Central type-bars and is pivoted at its rear end to a combined ribbon vibrator and escapement trip lever Z fulcrumed on the rear end of the movable frame B beneath the carriage.. The front end of this lever Z is connected to a ribbon vibrator Z which may be ofany suitable construction Aand its rear end is connected as by a rod Z2, to the carriage escapement (not shown) for actuating these devices. As both ends of the rod L and the parts to which it is connected are supported -by the movable frame B, it is not necessary for the pivot joint between the rod L and the uni-r versal bar to be on the pivot line for the frame B. as in the case of the joints connecting the type-bar links I to the key-supporting links z. The rod L is arched where it passes over the type-bar segment so as not to strike the latter when the machine is collapsed.

1I represents the space-bar which, as shown. is provided with end arms m and a middle arm m which like the arms of the universal bar are fulerumed on the pivot wire la in vertical slots in the upper edge of the cross-bar L. The middle arm m is connected by va link m2. Figs. 2 and 3 to a lever n which is preferably fulcrumed on the lower pivot wire It* in a sl t in the lower edge of the cross-bar with one end arranged to strike a projection n on the universal bar for moving the latter when the space bar is depressed. The lever n and link 'm2 are olnitted from Fig. 1 to avoid complicat ing this figure. As the slots in the crossbar L for tie .several key-supporting'links, and arms for the universal bar and space bar can all be cut at the same time by a series of suitable cutters arranged on a single mandrel, the cross bar is inexpensive to lnake. y

The upright parts of several of the key stems at the middle ofthe keyboard are offset` slightly between the pivots connecting them to the upper and lower links L z, as indicated at o in Fig. l. in order to clear ythe links I. The remaining key stems are not offset in this way. as the diverging lilies of the links I connected to them makes this unnecessary. The key stems. as seen in Fig. 4. are located at the outer sides of the links z except in the case of one of the stems adjacent tothe bar L which is located atf the inner side of the link to make room for the slots in the bar 7; which receive the middle arms. 7c and for the universal bar and space bar. The key actions and other working parts of the machine are returned to their normal positions by suitable springs which are not shown in. order not to confuse the drawings. Springs which partially support the weight of the shift frame are also omitted for the same reason.

By a comparison ot' Figs. l and T. it will be seen that the front end ofthe movable frame B. together with the space bar M and the low front bank of kevs G swing upwa rdlv and rearwardly while the other two banks of keys swing rearwardl and downwardly when the machine ls collapsed. Thisn'laterially shortens the machine from front to rear and reduces the height o't' itsl front end. As seen in Fig. 7, thev rear bank of keys lie close to the front ends of the type-bars and all of the keys lie below the elevation of the highest part of the stationary frame when the machine is collapsed, whereas some of the keys project to a higher elevation when 'in their operative position.

No claims are made in the application for certain of the features shown. such as the key actions. the arrangement of the universal bar. and the pivotal mountings for these parts and the space bar. as these features are claimed in another application.
